Loading-Unloading Procedures and Principles of Draught Survey for Bulk Carriers

This advanced course is designed for senior Deck Officers of Bulk Carriers to aid them in Planning, conducting and documenting Loading procedures

Intended Learning Outcome/s

After the training/assessment, the participant/s shall be able to:

• Explain the longitudinal stress acting during loading and unloading with regards to different cargoes
• Explain and understand the necessity for hatch cover inspection and tests
